My invention relates, more particularly, to machines for the manufacture of ozone and the distribution thereof into a room for purifying the air therein.

One ofvmy objects, generally stated, is to.

The machine shown, and constituting the preferred embodiment of my invention, comprises, generally stated, a base member 7, in the form of a housing; an electric fan structure 8; and an ozone-generating element 9.

The housing 7 is shown as of general cylindrical form and houses a transformerrepresented generally at 10 for stepping up, to the desired voltage, the current from main line wires, to be supplied to the ozone-generating element 9 as hereinafter described.

' therewith at '10 OZONE PURE AIRIIIER co.,

The transformer shown and which may be I of any desirable construction is connected at the terminals of its primar winding with wires 11 and 12, the wire 11 ing connected with one terminal of a rheostat 13the other terminal of which connects with a wire 14. The wires 12 and 14 connect with terminals of a fuse box represented at 15 and connected at other terminals thereof with wires 16 and 17 provided for connection with the line wires leading from any suitable sourceof current.

The secondary of the transformer 10 is grounded at one terminal 18 thereof on the base member 7, its other terminal being connected with a wire 19 which leads to the ozone-generating element 9.

The fuse box 15 also connects with wires 20 and 21 for supplyin line voltage current to the motor hereina er referred to and forming a part of the electric fan structure 8.

In the construction shown the coils of the transformer 10 are clamped between upper and lower plates 22' and 23 connected together by bolts 24 shown as held in place at the bottom of the base 7 by screws 25 screwing into the lower ends of these bolts. The

grounding of the wire 18 is eflected in the particular arrangement shown, by clamping itv between the plate 22 and one of the nuts 26 on the bolts 24.

The electric fan structure 8 comprises a metallic base 27 at which the structure is mounted upon the top of the base 7, the base 27 being shown as rigidly connected with the hollow base 7 and in electrical connection therewith, by screws, one only of which is shown at 28, these screws screwing into the top of the base 7.

The upper end of the base 27 is bifurcated at 29 and extending intothis bifurcated portion and adjustably pivotally. connected 30 is the upper section of the fan structure 8, the pivoting means 30, provided to permit of the swinging adjustment of the upper portion of the fan structure in a vertical plane, comprising, in the particular construction shown, diametrically opposed screws mounted-in the bifurcated portion 29. The upper portion of the fan structure comprises a plate 31 extending into the bifurcated portion 29 and containing diametricalopposed openings 32 into which the re- Y d i1ced,unthreaded, journalling ends 33 of the 6 screws 30 extend. The upper end of the plate '31 which is of reduced size and, for example, of circular form, carries a collar 34 secured thereto as by a set screw 35.

The plate 31 contains a socket 36 intersected by the openings 32 and into which a stem 37, depending from a motor-casing 38, is journalled, the motor casing 38 being rotatably supported on theplate 31 at a thrust washer 39 interposed between the top of the plate 31 and a depending boss 40 on the casmg 38 and from the lower end of which the stem 37 depends. I

The casing 38 contains a power device, such as an electric motor, positioned substantially horizontally in the casing and provided, on the outer end of the armature shaft 41 thereof, with a fan 42.

The fan device which comprises the motor casing, motor and fan, is thus mounted for oscillatory movement about a substantially vertical axis and in accordance with the preferred illustrated embodiment of my invention, is associated with means operating automatically to oscillate the fan device at its pivotal connection with the plate 31. These means may be of any suitable construction those shown being common and well known and comprising a link 43 having connection at one end with a crank pin 44 on the collar 34 and at its other end with a crank pin 45 on a disk 46 mounted on a shaft 47 journalled in an extension 48,0f the motor casing and driven from the motor shaft through a train of gears 49, 50, 51 and 52.,

The ozone-generating element 9 is shown as'located in the rear of the fan 42 at the upper portion of the latter and closely adjacent thereto and in vertical alignment with the axis about which the fan rotates, the element 45 9 being shown as supported directly on the 'motor-casing 38 as bymeans of angle brackets 53 located at opposite sides of the motor shaft and secured at their lower ends to the' motor casing as by screws 54, one only of which is shown.

Any suitable construction of ozone-generating element may be employed. That shown comprises a casing 55 of general recytangular shape with its lon est dimension 55 extending crosswise of the sha of the motor, the top and bottom plates of the casing 55 being solid and all of the surrounding walls thereof perforated as shown of the side wall illustrated in Fig. 1, this casing being se- 00 cured to the brackets 53 as by screws 56.

Located in the casing 55- are the energizable parts of the generating element 9 these parts comprising, in the particular device shown,

a series of parallel sheets 57 of current-con- 05 ducting material, as 'for example tin-foil,

each interposed between plates ,58 of dielectric material, as for example glass, these several sheets 57 being shown as connected with the wire 19.

The element 9 also comprises plate thembers 59 of current-conducting material,'as for example metal, each provided with series of points 60 projecting therefrom, these points,

by way of example, being formed by stamping them from the lmetal forming these sheets. The sheets 59 are so arranged, as shown that there will be associated with each sheet 57, two of the plates 59 one at each side thereof, with the points thereon projecting toward these sheets and preferabl in contact with the adjacent plates 58. llof the plates 59 are grounded on the casing 9, the intermediate ones of the plates 59 being connected with the upper plate 59 by connectors 61 to ground them on the casing 55, which latter is grounded through its connection with the motor casing 38.

In operation the fan 42 produces suction action on the ozone generated within the easing 55 and forces it into the air of the room in which the fan is located.

By mounting the ozone-generating element on the oscillating fan device, it is caused to oscillate with the fan which not only permits of this element being located close to the-fan and thus subjected to the strong suction action produced thereby, but also ensures uniform distribution ,of the ozone by the fan throughout the oscillating movements of the latter.

Furthermore, the machine, by reason of the incorporation therein of the features described, is not only of compact and pleasing appearance, but is rendered readily portable which, as will be understood, is a very desirable feature.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto, as the same may be variously modified and altered without departing from the spirit of my invention.

"What I claim as new, and desire to secure by Letters Patent, is: v a An ozone machine comprising, in combination, a hollow base, a transformer on said base, an electric fan structure comprising a lower body section mounted on said base and an upper section journalledto oscillate on said lower body section, means for oscillating said upper fan section, said upper'fan section comprising an electric motor device and a fan driven thereby, an'ozone-generating element located in the rear of the fan and over said motor and mounted on said up er'fan section so as to oscillate therewith anti present ozone to the action of said fan, and a flexible electrical. connection betweensaid transformer and said element.
